Hi, I'm trying to figure out if it's possible to get prestige weapon skins from MW2 (the "gold" skin) only in Warzone. I'm just grinding away, trying to get as many frags as possible with the M4 (I've already maxed out the M4), but the problem is the progress bar isn't moving. Oh, and I don't own the paid version of MW2 (I have the DMZ demo).
